 Hello boys and girls welcome back to part 7 of the EJ-25 build for the 06 STI In today's video. I'm gonna torque down the cam exhaust and intake sprocket bolts Timing cover goes back on engine mounts. I actually installed the engine mounts the other way around I'm gonna realize it when I'm gonna be installing the engine. I'm gonna have to rotate them 180 degrees later on And also the second half of the video is gonna be mostly about your PCV system positive crank venting system and oil catch cans and as always like subscribe comment Thanks enjoy Okay, so the clearance on this needs to be 0.05 or 1 millimeter. I Think half a millimeter is as close as you can get So I'm actually gonna push it away as much as I can and take my filler gauge and take 20.25 and 0.24 together make it a 0.49 it does not fit which means it's too tight So does that mean I can't use it? So looking at the instructions, okay, you need lactite blue glue Make sure there is a 0.04 Okay, so I can go to 0.04, okay So let's change these two Let's go 0.21 and 0.20 Okay, this is better No, it still doesn't fit. I don't know. I'm kind of scared to to use this. It's very close Let's see if a credit card will work So I got a card there goes in no issues. I Suppose I could drill the holes out a tiny bit to give me more Clearance, yeah, that's what I'm gonna do because 0.205 half of what I need is Not enough for me. I'm afraid the belt will wander and it will keep Sliding or scraping this and eventually break. So that's what I'm gonna drill these out Just the hair be right back and we're back. These are slightly bigger now You can already see the gap is much bigger still a bit tight. So point zero two and point zero two one It goes in here goes in here What doesn't go Here so I would need a tiny bit more here or maybe just leave it goes in here I mean once to it's very close. Let's see point Point zero three nine very close We think drill it out more or leave it. I'm gonna have to drill it out more It would not be able to sleep. Oh, yeah, this was point zero three two. This is point zero four one Just above the minimum Which is fine with me. All right tighten one a bit more so doesn't move remove the other Some blue blue or lock tight, but it's really it's blue a good amount. We don't want this thing coming out Torque was sixty so to sixty five inches of torque 65 which is barely something And there we go That's what we've got a nice even gap. So that's the timing boys and girls Done now you can torque it down the the cam sprocket bolts Back off a tiny bit. So the first step is twenty two point one on all four. So I'm gonna do twenty two Change it to inches twenty two Point one Okay, and now 45 degrees 91.6 it slips too easily and it sucks 37 110 Something's not right. I'm gonna do this one again Okay, just like what I came up with. Let's see if it's gonna work. I already torqued it down to twenty two point one So now it's the 45 degree angle. It's not gonna work for the Exhaust sprockets I'm going to leave this for now and think of a think of a better way Now that's that's out of the way I can put back these caps On the cam sprockets These are eight mil. I believe the torque to be four point seven. I'm gonna do five because that's the lowest setting on my Torque wrench Could be less than that, but you cannot find any solid information Coolant crossover pipe Uh-huh. I see a problem. I'm gonna have to move the oil pressure switch to its original spot Where it was on the 06 block So I guess they did change the crossover pipe in 08 28 foot pounds of torque That was just a guess You know what now that I have rtv ready. I'm gonna put a little bit here I was gonna go with rtv on the plug as well, but on second thought I'm gonna use red glue 38 in the plug All right back to the crossover pipe Much better. I had to clean the threads off on these Torque on these is 8.7. I'm doing nine Time for the engine mounts. All right, this one has an L L on it. So left side. So um driver's side. Actually this head is LH. So that's left hand So that's probably gonna go here. I wonder if they would fit Both sides No can't get them mixed up. These by the way are um cusco I think cusco mounts. I got them 12 years ago Or so one time Torque on these is 25.8 See how far you got it. You really want to recheck if you have bolts with lock washers You want to recheck them A few times All right, the intake is not mounted yet just Making final adjustments I did have to move these Screws around because they were hitting the coolant pipe here and also These fuel lines were also hitting the Cross pipe. So I had to bend these up Which was no issue at all. But now what I gotta do I want to get rid of the coolant passing through the throttle body. This is only to heat up the engine quicker So I don't need that on the track obviously So I'm gonna cap these this part off And where's the other one? And this here I'm just gonna put caps on it and then I'm proud I'm gonna get rid of this line because this this hooks up This hooks up here. So I'm gonna get rid of this line Right there. It connects to the to this hard line here. These are your heater core Lines for your for your heater So I'm gonna use This line that goes connects to the throttle body here. I'm gonna connect it to Where this one is. So that's just gonna keep flowing. Also, I am not Doing the factory oil catch System the pvp cv. I'm not using the factory one. I'm gonna install three catch cans Yes, three of them. So One for each head and one for the block. So I am not reusing these factory lines at all this stuff here All this so I actually have six connections. I have to do these two this one This one And these two here. All right. Check this out. So this is your pcv system positive crankcase ventilation system Remember before I was talking about the two openings on each head Then two more on the block, which is This one here and another one there. So that's your pc PCv valve right here this guy Connects to the intake manifold, which is right here. That's the that's the this is the back of the intake manifold Ignore this pipe here this from here Here here here and down there to the water pump. This is the coolant passage. This actually connects To the little pressurized tank right here. So as you can see These uh, these are believe are five eighths the male ends Coming out of the both heads The bigger one is five eighths. The smaller one is half inch. These five eighths are connected to each other This is also five eighths the one on the block the bigger one here. That's three fourths So the five eighths are just connected to each other one two and three I'm gonna take a good guess just to equalize the pressure between the two heads and the crankcase But the smaller the half inch one This attaches right here with the three 10 mil screws these these lines attached to the intercooler As you can see they go across and they connect to each other here Then here and then here back into the intake. This is your original turbo inlet pipe So the vacuum that's created inside this pipe It sucks in when this valve opens It sucks in the gases that are created Inside the heads and the the crankcase Same thing happens over here. There's a vacuum here. So whenever the pressure is too great Inside the the crankcase the valve opens And this also the vacuum created inside the turbo inlet pipe Helps it suck it in This here connects to your blowout valve Remember the intercooler is right here. So the blowout valve. I believe it's like somewhere over here So there's a pipe going into here I'm either gonna connect these two to one pipe and go into the One catch can then connect These two one catch can and then these two one catch can Or I may just leave What is it these the five eights Since these are just to equalize the pressure between the three I may just leave this This piping here get rid of this And connect one line To each catch can and this is what the catch can looks like So this is your inlet here and that's your out This like I'm gonna plug put a plug on it. Just like that. Also I don't have to unscrew the can To check the level Of the garbage that collects inside You got a little dipstick over here Which is a nice feature. Let's see what it looks like inside. So you see your basic Container so you can see the inlet It's right here and a little I was going to call it mesh, but you know a little filter. I guess whatever that would keep the the contaminated oil From going back into the engine and this will yes, it will go out into the atmosphere That's the whole point. So it doesn't go back into the engine out into the atmosphere. So that's how that's gonna look different sizes Of fittings whatever lines I'm going to use So this so this all came with in one box and I got two more here Now, why would you need a pcv system? What happens is when as the oil heats up it's You know at high temperatures it will even evaporate a little bit Create some kind of gases Inside the crankcase When the combustion part happens Not everything goes out into the exhaust Exhaust manifold in this case some of the exhaust gases fuel gets through the piston rings And gets into the oil so But since the the the burning temperature of fuel is much lower It will evaporate. So with all that all those gases that are created Inside the crankcase though though that needs to go somewhere Okay, if you don't have a if if you were to block The the block and and the heads Those gases would would find its way somewhere even either back through the piston rings Any of the oil seals gaskets, whatever it would it would find its way out So to prevent and then then you would end up with oil leaks and all kinds of problems The engine with every single engine Needs a pcv system of some sorts some kind of an oil catch can system some You know some some venting form, you know back in the old days I guess Cars classic cars classic muscle cars have those little filters on top of their valve covers. That's so The gases inside can evaporate through those little filters, you know something like like this So the benefit of an oil catch can what I'm going to be doing Is basically so in this system here all of those gases that are coming out get back into your intake And back into your combustion chamber again, but it's already that air is already contaminated. It's already dirty It's it's it's basically exhaust And your engine is burning that again. So obviously it's not good It's good for the environment But it's not good for your engine. So with this kind of setup where the The gases are vented into the atmosphere You know the the name tells it all no more dirty exhaust gases Going back into your engine They're they're going out into the atmosphere which helps your engine breathe better and cleaner And that's the whole point keep your engine clean inside Okay, so what I decided to do I'm going to get rid of these Or of these lines. I'm going to leave obviously the coolant line And since the the two heads and the black the crankcase are just connected just to equalize the pressure I'm going to leave that so I won't be cutting any of these lines So I'm going to remove the the turbo inlet pipe these lines And the the whole pcv valve And that's it. This is going to this is not going to be on the car any longer I am going to reuse this Shirt hose and we'll see on the other two remember I was talking about The the the coolant that passes through the throttle body from here To here. This is only to The warm coolant passes through so the air going into the engine Is warmer so it heats up the engine a little bit faster And then once it's once the coolant is hot Well, it it keeps on warming up that air And that's what we do not want So a simple fix I'm going to remove one of these Lines neither this one or that one Let's remove this one And simply connect this one here Just to close the loop Easiest mod ever All right, so I removed this clip here. I'm going to reuse it So this is going to go here Check out this tool cutters here. I don't know this might be a punch Made in the usa I'm guessing maybe 80s or even 70s Perfect for this now this adapter here. This is quite big. This is three quarters by the way Okay, much better. I'm going to remove these two All right, so this part of the pcv system is done Along with the coolant pipe. So the catch cans I will connect Once I once the engine is in I'm going to figure out Where I want to mount the three catch cans And it's just going to be a matter of connecting each Each head and the black That's exactly how that's going to look And this is going to be mounted somewhere In the engine compartment. So I will get hero hoses Like this one here, but that's later. Now it's time for the intake manifold
